Application of magnetic chitosan composites for the removal of toxic metal and dyes from aqueous solutions

Reddy, D. Harikishore Kumar, Lee, Seung-Mok·2013·Advances in Colloid and Interface Science

Abstract

Magnetic chitosan composites (MCCs) are a novel material that exhibits good sorption behavior toward various toxic pollutants in aqueous solution. These magnetic composites have a fast adsorption rate and high adsorption efficiency, efficient to remove various pollutants and they are easy to recover and reuse. These features highlight the suitability of MCCs for the treatment of water polluted with metal and organic materials. This review outlines the preparation of MCCs as well as methods to characterize these materials using FTIR, XRD, TGA and other microscopy-based techniques. Additionally, an overview of recent developments and applications of MCCs for metal and organic pollutant removal is discussed in detail. Based on current research and existing materials, some new and futuristic approaches in this fascinating area are also discussed. The main objective of this review is to provide up-to-date information about the most important features of MCCs and to show their advantages as adsorbents in the treatment of polluted aqueous solutions.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • To apply biochar at large scale for removal of organic and inorganic pollutants from wastewater, it is necessary to clearly know the adsorbent surface area, diffusion mechanisms and chemical reaction involved in the adsorption process through the intra-particle diffusion model.

    “Reddy and Lee (2013) reported that to apply biochar in large scale for the removal of organic and inorganic pollutants from wastewater, it is necessary to clearly know the adsorbent surface area, diffusion mechanisms and chemical reaction involved in the adsorption process thorough the intra-particle diffusion model.”
  • Chitosan contains a large number of amino and hydroxyl functional groups and possesses excellent adsorption ability for heavy metals, dyestuffs, and pathogens and can be easily functionalized.

    “Chitosan contains a large number of amino (-NH 2 ) and hydroxyl (-OH) functional groups and possesses excellent adsorption ability for a wide variety of environmental pollutants such as heavy metals, 62 dyestuffs, 62 and pathogens 63 and can be easily functionalized.64”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
